Our AFM & DFM Disabler disabler will keep your GM vehicle in V8 or V6 mode all of the time, preventing it from disabling any cylinders.

This will give your truck more power & performance while also reducing the likelihood of the dreaded lifter failure.

We have tested and designed our disabler to have the lowest power drain of any competitor on the market. With only 0.71mA of current draw it would take 84,500 hours, or 9.6 years, for our device to drain a fully charged battery.

While other devices will drain your battery in a week or less we have tested ours for over a month with negligible drain and no issues starting the vehicle.

Lifter failure can directly be attributed to the active and dynamic fuel management systems constantly turning cylinders on and off. Keeping your engine running all of its cylinders all of the time is the best way to decrease the likelihood of experiencing lifter failure.

With your engine constantly flipping back between V4 and V8 modes, there is a noticeable hesitation in acceleration when you press on the gas pedal.

Disabling these systems will allow your engine to run smoother while also providing more throttle response and giving you access to all of your engine's power whenever you need it.

The BOOST AFM/DFM Disabler does not flash your ECU. It simply plugs into the OBDII port and begins working within seconds. Because it doesn't flash the engine's computer you can safely remove the device without leaving any trace that it was ever there. Simply unplug it for any warranty or dealership visits and you won't have any issues with voiding your warranty.
